EVALUATION AND UTILIZATION OF AIRPLANE FLIGHT LOADS DATA. PART I. TECHNIQUES AND UNCERTAINITIES.
Abstract
The report summarizes the important factors to be considered in flight loads investigations. Flight loads are defined as the forces and moments to which an airplane structure is subjected while the vehicle is airborne and are treated here as random phenomena. Evaluation of flight loads then consists of estimating the statistical properties of the underlying processes from sample measurements. Methods which are appropriate for this purpose are discussed in the report along with the associated estimation errors. Current methods for computing loads from flight data are reviewed and analyzed. Then the utilization of the computed loads in structural design applications is described. The data requirements for both design criteria and design substantiation are discussed. Operational flight loads data are covered under the latter heading. (Author)
